What Is Macadamia Good For?

Are macadamia nuts healthy? With their rich nutrient profile, macadamia nuts can be used to improve your health in a variety of ways. Here are the top 8 benefits of macadamia nuts that are scientifically proven.

#1. They reduce the risk of heart disease.

In general, nuts are good for your heart because of their healthy fat content. Macadamia nuts are no exception.

Research shows that macadamia nuts contain a unique fatty acid profile that benefits lipids and lipoproteins to reduce the risk of cardiovascular disease. They also reduce total and LDL or “bad” cholesterol (2).

One study found that when compared to the average American diet, a macadamia nut-rich diet lowered total cholesterol and improved the lipid/lipoprotein profile of hypercholesterolemic men, which reduces the risk of cardiovascular disease.

#2. They reduce inflammation.

Nuts are natural sources of antioxidants, which can be used to reduce inflammation in the body. One study found that a diet high in macadamia nuts and other mixed nuts reduces C-reactive protein and oxidative stress (3). Both factors are indications of underlying inflammation that can increase the risk of chronic diseases and contribute to various unwanted symptoms.   

#3. They can help you lose weight.

There are several ways in which macadamia nuts can help you lose weight, First, macadamia nuts are high in fiber, which increases satiation and delays gastric emptying and absorption. In other words, they help keep you full for longer periods of time so you consume fewer calories (4).

Next, macadamia nuts contain unsaturated fats, which are more readily oxidized than saturated fats. This means that they are less likely to lead to fat accumulation (5). Additionally, the high fiber and unsaturated fat in macadamia nuts may lead to an increase in diet-induced thermogenesis and in resting energy expenditure to help you maintain your weight (6).

Finally, research shows that macadamia nuts lead to the loss of available energy due to increased fecal losses of fat because of the incomplete mastication of whole nuts (7). In other words, whole nuts aren’t digested as easily as nut butter is, which means you don’t absorb it as well. 

#4. They are ideally suited for the keto diet.

Although they are high in fat, macadamia nuts are among the lowest in protein (8). They are also low in carbs, which makes them ideally suited for the keto diet. 

Keep in mind that many nuts are high in carbs, fat, AND protein. But macadamia nuts meet the strict requirements of the ketogenic diet because they contain high amounts of fat and low amounts of protein and carbs so you can add them to your diet and stay in ketosis.

#5. They can help manage type 2 diabetes.

The fat and fiber found in macadamia nuts can help manage type 2 diabetes. Research shows that the monounsaturated fats in nuts such as macadamia nuts significantly reduce fasting plasma glucose in people with type 2 diabetes. Eating macadamia nuts also helps improve triglyceride markers, HDL cholesterol levels, body weight, and blood pressure (9). 

Additionally, the fiber in macadamia nuts helps slow down blood glucose dumping to help keep your levels stable.All of these factors help reduce the risk factors associated with developing type 2 diabetes. 

Another study found that eating monounsaturated fats, such as the ones found in macadamia nuts, is more effective at improving blood sugar levels when combined with exercise than exercising alone (10). 

#6. They contain tocotrienols to help support the brain and protect against cancer. 

Tocotrienols are antioxidants that belong to the vitamin E family. Macadamia nuts are high in vitamin E. When you eat them, you greatly increase your tocotrienols levels in the body. 

Research shows that tocotrienols can be used to protect against cancer (11) and keep your brain healthy. They work by destroying free radical damage in the body to protect various parts of your health and reduce the risk of serious diseases (12). 

One study found that tocotrienols also protect your brain cells from the excitatory neurotransmitter glutamate (13), which contributes to anxiety and other neurological conditions such as Alzheimer’s and Parkinson’s disease. 

#7. They can help boost your immune system.

Macadamia nuts are high in antioxidants such as vitamin E and selenium, which helps neutralize free radical damage to boost immune health (14). Macadamia nuts are also high in fiber and have a prebiotic effect on the digestive system to increase your good gut bacteria (15). 

This is important because almost 80 percent of your immune system resides in your gut. So keeping your gut healthy is an important part of boosting your immune health. 

#8. They contain over 200 percent of your daily recommended intake of manganese (per 100-gram serving).

Manganese is an overlooked mineral with important functions in the body. It helps activate enzymes and acts as an antioxidant in the body (16). Manganese also aids in bone formation, wound healing, and metabolism. 

A 100-gram serving of macadamia nuts provides you with more manganese than you need for the entire day. We realize that you’re unlikely to eat 100 grams in one given serving, but even half of the amount would give you what you need.
